Erie County's Office of Geographic Information Services (OGIS) addresses the GIS needs of the County's government, its 44 municipalities and its 919,040 residents. To serve the County Government, the OGIS produces and distributes geographic data, creates maps, provides GIS technical support and develops and hosts web-based mapping services catered to the specific needs of interested departments. In addition to distributing geographic data and providing technical support to the County's municipalities, the OGIS assists local governments by holding GIS User Group meetings, by working toward the development of county-wide GIS procedures and standards, and by hosting the Internet Mapping Consortium.

The Erie County Office of GIS provided services and expertise to the Emergency Management Civil Defense/Disaster Preparedness Division in creating the ReadyErie App.

The app is available for Erie County residents to make and share emergency plans, with checklists for emergency kits, as well as displaying the location of shelters, hospitals, fire stations, and police departments, and the condition of emergency routes. This app also provides information from Erie County during emergencies. Press Release
